PROBLEM TO BE SOLVED : To provide a production method of a novel NdFeB-based magnet having a coercive force at higher temperatures, by densifying to bulk through sintering without adding a large amount of a rare metal such as Dy, Tb, and Co. SOLUTION : This production method of an NdFeBGa magnet having a high coercive force is a production method, by producing a quenched ribbon of Nd-Fe-B-GX (x is a number representing atomic ratio and satisfies the equation : 1≤x≤3) and by pressurizing-sintering the produced ribbon.
